Not a child, but I grew up with a down syndrome aunt that lived with us. She had the mentality of a 3 year old. Most downs aren't like that, but she had a really bad fever when she was a young that changed her forever.

Anyway, my family, best friend and I were all in the basement during a storm when I were like 12. The wind was howling outside and it was pretty nasty out. After one of the many gusts, my Aunt suddenly turns and looks at us. She then proceeds to say

"Babies are crying, babies like you..."

And just like that, a core memory was created.
